What P2E16 means
P2E16 flags a position reading from the intermediate shaft selection actuator that is electrically valid but not credible, for example a travel that does not match the commanded movement or the learned end stops. No manufacturer documents P2E16 publicly. Why learned references matter is explained in Ford's DPS6 dual-clutch summary from 2012: its clutch actuators sense motor position with Hall elements that only count steps, so the system must sweep from one end stop to the other to know the absolute position. If counts are lost or the mechanism no longer reaches its stops, the computed position drifts away from reality. GM judges plausibility of a rod sensor against shaft speeds (P2832 in 23OBDG07). A relearn after battery work or repair may clear the fault; otherwise check the mechanism.
P2E16 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyHard
- Typical labor0.5 to 4 hours
- Clears after repairAfter a drive cycle
Symptoms of P2E16
- Harsh, slow or failed shifts involving the intermediate shaft
- Transmission warning, possibly limp mode
- Fault returns until a relearn has been done
Common causes of P2E16
- Most likelyEnd stops not learned or lost after battery disconnect or repair
- PossibleActuator or selection linkage binding, target position not reached
- PossibleSensor or its magnet shifted, reading offset
- Less likelyControl software needs an update
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What to do next
- Note P2E16 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E16
What does P2E16 mean?
P2E16 means "Intermediate Shaft Selection Actuator Position Sensor Range/Performance". P2E16 flags a position reading from the intermediate shaft selection actuator that is electrically valid but not credible, for example a travel that does not match the commanded movement or the learned end stops. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E16?
Drive gently and only to a workshop. With P2E16 the car can go into limp mode (reduced power) to protect itself.
Will P2E16 fail an emissions test?
Yes, it can. P2E16 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P2E16 to fix?
Difficulty: hard. A typical repair takes 0.5 to 4 hours of work. This is a job for a workshop.
Will P2E16 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
